Abstract (en)
[origin: WO2020115617A1] A rotor assembly of a water pump is provided including a rotor body, an upper bearing, a lower bearing, a magnet, an impeller, and a shaft. The rotor assembly also includes a rotor shaft core that ensures concentricity of the upper bearing, the lower bearing, the magnet, and the shaft. The present disclosure also provides a manufacturing method that involves overmolding the rotor body onto the rotor shaft core to encapsulate the magnet.
